Heritage Audio 80 series 6673 Mic Pre 4 Band EQ

The 6673 is a 73-sized module, adding the 1066 mid band to the 73 classic design, creating a 4 band tone monster that is really hard to beat. In addition, the 73 mid band has been expanded in frequency choices, with the classic 73 ones kept untouched. It also features a Baxandall type High shelf band, but with the
addition of a high frequency selector switch offering 3 different
frequencies instead of the fixed one at 12 kHz.

The result is a 4-band tone monster that combines the best features of the vintage modules in an incredibly smart and tasteful way, at a price that beats most current offerings.

Vintage connoisseurs already know how sweet and powerful the 1066 mid band sounds and how well it complements the 73´s.

Special care has been taken in sourcing the correct components that not only ensure that performance will be as close to a 1970´s unit as possible nowadays, but also gives your top-class studio the look and feel it deserves.

Custom polystyrene and film capacitors have been developed to closely match the Siemens styroflex and Mullard Mustard types of the late 60s and early 70s.
